== Function ==
[https://www.uniprot.org/uniprot/PETH_PISS1 PETH_PISS1] Involved in the degradation and assimilation of the plastic poly(ethylene terephthalate) (PET), which allows I.sakaiensis to use PET as its major energy and carbon source for growth. Likely acts synergistically with MHETase to depolymerize PET (PubMed:26965627). Catalyzes the hydrolysis of PET to produce mono(2-hydroxyethyl) terephthalate (MHET) as the major product (PubMed:26965627, PubMed:29235460, PubMed:29374183, PubMed:29603535, PubMed:29666242, PubMed:32269349). Also depolymerizes another semiaromatic polyester, poly(ethylene-2,5-furandicarboxylate) (PEF), which is an emerging, bioderived PET replacement with improved gas barrier properties (PubMed:29666242). In contrast, PETase does not degrade aliphatic polyesters such as polylactic acid (PLA) and polybutylene succinate (PBS) (PubMed:29666242). Is also able to hydrolyze bis(hydroxyethyl) terephthalate (BHET) to yield MHET with no further decomposition, but terephthalate (TPA) can also be observed (PubMed:26965627, PubMed:29374183, PubMed:29603535). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) in vitro (PubMed:26965627, PubMed:30502092).<ref>PMID:26965627</ref> <ref>PMID:29235460</ref> <ref>PMID:29374183</ref> <ref>PMID:29603535</ref> <ref>PMID:29666242</ref> <ref>PMID:30502092</ref> <ref>PMID:32269349</ref>
